2. What Is Galvanized Wire?
Galvanized Wire is steel wire coated with a protective layer of zinc, produced through hot-dip galvanizing or electro-galvanizing. This coating acts as a barrier against corrosion, significantly enhancing its life expectancy and mechanical reliability in hostile environments.
Applications: Security fencing, cable armoring, agricultural mesh, overhead power lines, nails & fasteners, basketry, vineyard support, filtration, and much more.
Key Attributes: High tensile strength, ductility, superior corrosion resistance, cost efficiency, and adherence to international standards (such as ISO 7989, ASTM A641, BS 443).

5. Galvanized Wire in Application: Technical Advantages
- Corrosion Resistance: Zinc layer protects structural steel from water, salt, alkali, extreme weather & chemicals. Hot-dip galvanizing achieves 7-10+ years longevity in outdoor exposures based on ASTM B117 salt-spray testing.
- High Tensile Performance: Ensures reliability for fence, cable armoring, utility, and high-load structures.
- Low Maintenance: Galvanized finish reduces the frequency and cost of repair and replacement, shrinking life cycle costs by over 35% compared to untreated wire (American Galvanizers Association).
- Versatile Surface: Smooth, burr-free, formable, and weldable, making it ideal for automated installations.
- Environmental Friendliness: Both steel and zinc are fully recyclable, meeting green building criteria such as LEED.
Certifications & QC: Most recognized brands manufacture Galvanized Wire in compliance with ISO 9001, ISO 14001, REACH, ROHS, and CE directives.
Third-party inspection with SGS and Bureau Veritas is commonly available.

10. Frequently Asked Technical Questions (FAQ) about Galvanized Wire
Q1: What material grades are commonly used for Galvanized Wire?
A: The most frequently used are Low Carbon Steel (Q195, Q235, SAE 1006/1008, SWRH 42A). These are selected for their excellent formability, weldability, and strength-to-weight ratios. High carbon options (e.g., 65Mn, SAE 1070) are applied for spring wire and high-tension use.
Q2: What standards govern Galvanized Wire production?
A: Key standards include ISO 7989, ASTM A641/A641M (US), BS 443 (UK), DIN 1548 (EU), and GB/T 343 (China). Compliance assures dimensional, surface, strength, and zinc thickness consistency.
Q3: How is zinc coating thickness measured & controlled?
A: Thickness is measured according to ISO 1461 or ASTM E376 by magnetic induction gauge or XRF. Quality plants use automatic online measurement for process accuracy.
Q4: What is the recommended installation standard for Galvanized Wire fencing?
A: Installation should adhere to ASTM F567 and local engineering standards. Wires must be tensioned using industry-approved stretchers and anchored with proper galvanized fasteners for optimal lifespan.
Q5: Does Galvanized Wire rust? What is its typical service life?
A: It resists red rust due to sacrificial zinc; however, in seaside or industrial zones, heavier coating (≥60g/m2) is preferred. Service life is typically 7–12 years outdoors (source: GAA, ASTM B117 accelerated test).
Q6: Can Galvanized Wire be welded or painted?
A: Yes. Welding is possible using standard MIG with galvanized electrodes, though some zinc loss at joints occurs. For paint, apply after degreasing for enhanced adhesion. Epoxy and PPC coatings further reinforce longevity.
Q7: What is your typical lead time & trade terms?
A: Regular orders: 7–15 days. Urgent/bulk: priority slot possible. Terms: FOB, CFR, DDP, LCL/FCL container111. Standard documentation: CO, Mill Test Certificate, SGS/BV third-party inspection per shipment.
